This building and the area around it has TONS of venders and retail stores (Gap, etc). You can buy just about anything.
All the references I could read about Quincy Market talk about open-air cafés and streets artists, but I cóuldn´t see nothing of that.-
Just behind Fanehuil Hall are the shops known as Quincy Market, with double corridors of glass-canopied restauarants, boutiques and specialty shops.-
Is a very nice place, you can find music, artist that show their talent, good places to eat (different prices and flavors)....
